Description

Technical Field

[0001] This utility model belongs to the field of filter membrane tooling technology, specifically relating to a press-type multi-stage filter membrane sample preparation device. Background Technology

[0002] Currently, to detect and analyze residual particulate impurities on the surface of machined metal parts, the metal parts must first be cleaned, followed by filtration and extraction from the cleaned liquid. This is typically done using a filter holder with filter membranes to retain substances insoluble in the liquid. To more effectively connect the filter holder to the cleaning equipment, a filter membrane sample preparation device is usually used as a clamp for the filter holder to facilitate operation.

[0003] However, traditional filter membrane sample preparation devices are cumbersome to install and remove, requiring installation and replacement only in relatively fixed positions. This results in limited space, poor visualization, and inconvenient operation. Therefore, a press-type multi-stage filter membrane sample preparation device was designed to address these issues.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art.
